Police say MGM casino records show Johnson spent more than $90,000 last year in penny slots.

"I paid for the football games, for the homecoming tickets, I don't know if any of my money was used at the casino or not - that's abysmal," said Peter Dedha, former student.

The sheriff's office says not only did a search of Johnson's classroom reveal several casino receipts -- but also, opened and empty homecoming envelopes.

Johnson was arraigned on one count of embezzlement from a non-profit has been granted a $10,000 personal bond. FOX 2 was unable to reach her for comment Thursday.

"For a teacher like this that I've heard so many good things about, it's just shocking," said Dedha.

Many students and parents are hoping Johnson gets some help.

"She's going to have to face justice," said parent Stephanie Bialas. "For the parents out there, we fight to work to get our kids the best education and the best additional things to do. It's not right."
